RTX 4090 PCIe 3.0 vs PCIe 4.0 - How Big is the Difference?

So i dont need to worry about the generation with MSI a320 with 3060

Proving you don't have to limit yourself to PCIe 3.0 cards if seeking the best possible card for an older PC.

มี test 4080 ไหม

This proves that 4090 should have been pcie 5.0. 4.0 x16 was faster than 3.0x16 so 3.0 was out of bandwidth. Many people are in a situation where their 4090 is running at 4.0 x8. Those people are losing performance. If the card was 5.0 there would be a lot of people running 5.0 x8 and that would be fine, but no

Perhaps testing them on 13900k and 10th gen intel would be more relatable to us consumers as we don't need to know the difference when we've already owning a 13900k right?

TL:DW version: if you have an older motherboard but still a good enough CPU in it and wonder if you need a full system upgrade to use a better GPU, you don't.

what board on socket lga 1700 supports pcie3????

Hey, thats to less difference for the bucks! Thank you for the test!

Little TO GOOD Diference in some games (3 UP 10 FPS).

So it means pcie 4.0 could be rocked for easily some more years as we have just hit the line with pcie 3.0 and it's negligible so you could use it until your Mobo gets wrecked

Excuse my ignorance, I have a question about the test, where could the author find a motherboard with support for i9 13900k and at the same time an interface for connecting pci-e 3.0 video cards?

thx for vid bro, can u test 4090 with 16 lanes and 8 lanes? atm i can only use 8 lanes because of my 2 NVMe ssd....

Big different will on CPU level

Great test. Other testers will be testing this at 1080p like anyone who bought this card will be running it at that rez

pcie 5.0 8x vs pcie 5.0 16x. I would love to see that for a potential nvme gen 5 ssd in the future.

100% within margin of error.....no need for it yet, same when we first got pcie3....
Just market hype.

Bueno, 7 fps a 4K ya es diferencia, es una gran cantidad de información procesada en una fracción de segundo.

So difference is too low that is not worth the extra money.

I guess I’m just blind at this point I don’t really see a significant difference.

So, the Only card that is bottlenecked by PCIe 3.0 is the 4090? or are other cards also benefitting like the RX 7900XTX?

If youve got a b450 era board, dont bother. You can still 5800X3D + 4090 and crush everything at 4k and 1440P. Only at 1080P does it actually make a diff on the CPU/ram for the most part.

impact = 0%
Thanks.

It is interesting to see these numbers with only 1-10% differences. I'm would like to see a bit more movement than just running in the field of view, which would test the cpu, card and the transfer rates fully. I have noticed the Spiderman graphics in other demo comparisons are more stuttered when Spidy is swinging causing quicker full scene changes. Lots of motion may be more difficult to duplicate video to video. IMHO

Can it run hogwarts though?

PCIe 3 was sooooooooo laggyyyy
thanks to them for inventing PCIe 4 :V

When u play in 2k or lesser it wont have a much different but if it 4k or higher i think pcie 3 will bottleneckin the pcie bus

i9 13900k pcie 3.0? mmmm

bus saturation in games is generations off. Really only get bus saturation in simulations and the equivalent. The difference in FPS is basically just the signal quality of the bus

Both PCIes are on x16 correct...?

Interesting. Tad steady reduction of latency, but debatable power consumption, vs slight fps increase.

Obviously almost no difference for games yet lot of people are so fixated on latest tech and future-proofing which simply doesn't exist when comes to PC hardware.

if you have already PCIe 3, you really don´t need an upgrade. the improvement is marginal.

so basiucally. 3.5%

It doesn't' make much difference now, but this future proofing and progression. Games will get larger and will need to have more data transferred faster . Then the larger bandwidth will start to come into play. Imagine trying to use a PCI 3.0 bus in about 5 yrs with a new AAA game in 2028.

Fortnite?

Realistically there shouldn't be any difference. The GPU is not there yet. I guess the motherboard had other chips that were better in PCIe 4.0

Bah just marketing lol pci 3.0 and pci 4.0 and 5.0 and 6.0 and 7.0 lol running the same the diference its only en speed storage lol

As the bios settings doesnt do much more in re tuning the pcie lanes

Dont scam people dude

How do you test 3.0 in 13900k?

rdna3 is more efficiently using system resources...if ur not running the aaa i9/r9 ddr5 setup then last gen nvidia is a no-go regarding efficiency in gaming

So max 10 fps difference.


Gen 3 vs gen2 was around 0-3 fps difference

Короче на уровне погрешности,выходит можно камень с 3 версией брать по бюджету

Sono tutte stronzate per farci venire voglia di cambiare sempre hardware come nei telefonini cha da anni aumentano un po' la ram poi la telecamera e la pila dopo 2 anni è futtuta

wow, very big differernt about faster 20fps - 50fps in low 0.1%.

These benchmarks should have been done at 1080p

How do you set it to pcie 3.0 on a 13th gen intel chip? Is there a bios setting or something? Or is that the ssd speed?

Wow 3 fps
